The whole request
Publish the next version of the Swarm Derby site under its existing name. The change is GitHub commit ebf6f2d: the game page, the agent bot and the agent docs move to SwarmDerby v2 (a signed house draw replaces the block-hash draw) and its DerbyAuction, and agent.md pins the swarm-derby-mcp build for v2. Seven files are replaced with the files from that commit.

I replaced the five files with the versions from commit
ebf6f2d6c34283d84e58ea8075b75251dfa285cd, byte for byte, and changed nothing else. All five match the required sha256 values.File Change agent-bot.mjs+19 / −5 agent.md+20 / −14 README.md+7 / −4 specs/README.md+4 / −2 specs/WP6-operator-runbook.md+4 / −2 How I checked:
- I downloaded each file from raw.githubusercontent.com at that commit and confirmed its sha256 matched before copying it into place, then hashed it again in place.
git statusshows only these five files modified, with nothing added or removed.agent-bot.mjspassesnode --check. That is a syntax check only: I did not run the bot against the chain. Its diff is the expected v2 change: the block-hash wait is replaced by waiting for the house draw, with a call toexpireif no draw arrives within 5 minutes.
Not done, and why:
- The other two of the "seven files": the task says seven files are replaced, but this assignment lists only five and allows only those paths. The other two are most likely
index.html(the game page) and its sourcedev/game.html. Neither is updated here, so the page still points at the v1 contract while the bot and docs describe v2. - The published site: I did not touch
dist/(also outside the allowed paths). Earlier versions were published by copying the root files intodist/, so it still has the oldagent.mdandagent-bot.mjs.
Someone needs to update the game page and refresh
dist/before this version is published.I haven't committed anything; the changes are in the working tree.

Review complete. The findings file holds three low-severity advisory items and nothing that blocks hosting.
Verdict: the site can be hosted. No critical or high finding. Every hosted file was read:
dist/index.html(markup, the inlined fonts and Tailwind CSS, the bundled ethers and js-sha3, and the full game script),dist/agent.md,dist/agent-bot.mjs,dist/LICENSE,dist/NOTICES.md, both theme packs andthemes/index.json, plus the source they were built from.What I verified:
dist/is byte-identical to the root files, andindex.htmlreproduces fromdev/game.htmlwith only the font and Tailwind insertions the build script makes.- The bundled ethers 6.13.4 and js-sha3 0.9.3 match the npm registry tarballs byte for byte. The ethers line has not changed in any commit of the page.
- The page loads nothing external except the Robinhood RPC and its own theme files. No iframes, redirects, eval, dynamic imports, external scripts or tracking. The only outbound link targets are x.com profile handles that pass the theme validator.
- Approvals are exact-amount, to the derby or auction contract only. The quick-swing key signs nothing but its own consent. No seed phrase or password prompts.
- On chain: the new derby and auction addresses hold code, both reference the IMD token, the auction's derby pointer is the v2 derby, prices match the page, and DRAW_WINDOW and REVEAL_WINDOW are 300 s as the page assumes.
- On a local fork of the chain I ran the page's exact flows against v2: buy, quality-0 swing (resolves in one transaction), committed swing with
committedAtin the event, early finalize and early expire revert with the error names the page decodes, expire after 300 s refunds the turn, the quick-swing consent is accepted with the page's EIP-712 domain, a session key can swing and expire for the player, and an auction bid in the page's format succeeds. - The theme validator passes both packs and the PNGs have the required dimensions.
Findings recorded in
.imd-findings.json, all low:dist/agent.mdline 138 still says the last reveal closes about 25 seconds after midnight. On v2 it is up to 10 minutes, as the page and the Loop section already say.dist/index.htmlline 2270 stores the quick-swing private key in plaintext localStorage before the on-chain authorization confirms. Pre-existing and documented in the README as accepted.- The game page never says on screen that live rolls now depend on an operator-held house key. The explanation lives only in a code comment and in agent.md.
Not verifiable from this sandbox: GitHub, Blockscout and the legacy site domain were blocked, so I could not compare the files to upstream commit ebf6f2d, confirm the pinned MCP commit exists, or confirm that

The hosted agent docs were moved to SwarmDerby v2, where a swing can be revealed for up to 10 minutes after its commit (DRAW_WINDOW 300 s plus REVEAL_WINDOW 300 s; both constants read 300 on the deployed v2 contract 0x53d9aa0b925c5148bcc5f98f394872687f4c831c).
The Loop section (line 44-45) correctly says 'within 10 minutes of committedAt' and the game page was updated to 'Payout opens within 10 minutes' (dist/index.html line 2076), but the Payouts section still carries the v1 wording 'about 25 seconds'. An agent that settles on that figure will call settleNextDay too early and get DayNotOver.
Advisory: documentation text only, nothing unsafe is hosted.
Open dist/agent.md and read line 138: it says the last swing can no longer be revealed 'about 25 seconds' after 00:00 UTC.
Compare with line 44-45 of the same file ('Reveal within 10 minutes of committedAt') and with
cast call 0x53d9aa0b925c5148bcc5f98f394872687f4c831c 'DRAW_WINDOW()(uint256)'and'REVEAL_WINDOW()(uint256)'on https://rpc.mainnet.chain.robinhood.com, which both return 300.Expected: 'about 10 minutes'.
Actual: 'about 25 seconds'.
Quick-swing session private key is written to localStorage in plaintext, before the on-chain authorization is confirmeddist/index.html:2270
enableOrTopUpSession() creates a random wallet and stores its raw private key under the localStorage key swarm_derby:session:::, then asks the player's wallet to call setSession and to send up to 0.002 ETH to that key. Any script or extension running on the page origin can read the key and spend that ETH and the player's turns.
The maintainers document this as an accepted risk in README.md (not hosted) and the on-page text says only 'It can only spend your turns; winnings always go to your wallet.' The key is written before setSession is confirmed, so a cancelled authorization still leaves a key behind. Pre-existing behaviour carried over unchanged into v2; advisory only, it is not a drainer (the key can only move its own small gas balance and the player's turns, never the player's wallet or IMD).
Open dist/index.html on the hosted site, press CONNECT, switch to LIVE, press ENABLE QUICK SWINGS and confirm the two wallet prompts.
In the browser devtools Application tab, open Local Storage for the site origin: the entry swarm_derby:session:4663:0x53d9aa0b925c5148bcc5f98f394872687f4c831c: holds a 0x-prefixed 64-hex private key in clear text.
Expected: key encrypted or kept outside page-readable storage.
Actual: plaintext key readable by any same-origin script.
Game page never tells the player on screen that each live roll now depends on an operator-held house keydist/index.html:2461
This version replaces the block-hash draw with a signature from the operator's house key: the roll is keccak(player salt, house draw) and the house can withhold a draw (turn returned) and, as agent.md states, 'The holder of the house key can compute every draw, so it does not play'. That trust assumption is explained only in a JavaScript comment (lines 1836-1841) and in agent.md (lines 49-51), which arcade players are not pointed to.
The player-facing strings say 'Waiting for the house draw…', 'The house did not draw within 5 minutes' and the receipt is labelled 'ON-CHAIN · ROBINHOOD CHAIN', with no on-screen sentence saying who the house is or that a house key holder who also played could steer results.
Advisory: it is a disclosure gap, not a deceptive claim; the page makes no 'provably fair' statement and the reveal transaction it links is real.
Open dist/index.html, press CONNECT, LIVE · IMD, buy a pack and swing.
The ticker shows 'Swing committed.
Waiting for the house draw…' and the receipt shows 'ON-CHAIN · ROBINHOOD CHAIN'.
Search the rendered page text (not the script) for 'house key' or 'operator': no match.
The only explanation is the comment at dist/index.html lines 1836-1841 and dist/agent.md lines 49-51.
Expected: a visible line such as the one in agent.md.
Actual: none on the game page.
